Someone should.  "I think I'll throw in a new spring" is a cute thing to say if 
never done it!  It is definitely a b*tch, at least the first time.  Yeah, 
rebolting the 
center cap is the hardest part -- for my two cents, I would say that your life 
is made 
easier if you MAKE CERTAIN your center housing is centered on the spring itself 
attempting the rebolt.  Use the horizontal bolt as an eyeball guide, and make 
sure the 
bottom leaf is centered against the others -- i.e., ascertain that the spring 
eye gaps 
are equal at both ends!

Charlie Brown suggested another trick for bolting down the center housing 
(which I did 
not need to use) -- and that is to find another long bolt the same size as the 
studs, file its end to a taper, and use it for locating your bolt-ups. 

In any case, allow some time for the job, and be kinder and gentler while you 
do it.
